Parameter.ViewState Property

Gets a dictionary of state information that allows you to save and restore the view state of a Parameter object across multiple requests for the same page.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

[<BrowsableAttribute(false)>]
member ViewState : StateBag

Property Value

Type: System.Web.UI.StateBag
An instance of StateBag that contains the Parameter object's view-state information.

A parameter's view state is the accumulation of all its property values. To preserve these values across HTTP requests, ASP.NET server controls use this property, which is an instance of the StateBag class, to store the property values. The values are then passed as a variable to an HTML hidden input element when subsequent requests are processed. View state is enabled for all server controls by default.

For more information about dictionaries and how to use them, see Collections and Data Structures.

The following code example demonstrates how to use the view-state object to store parameter object state in a class that extends the Parameter class. This code example is part of a larger example provided for the Parameter class overview.
